When generating irregular waves with a duration of 500 seconds using HOS-NWT, an amplitude aliasing issue has occurred.

Dear Author,

I am writing to seek your advice on an issue I have encountered while using HOS-NWT to generate irregular waves. Specifically, when setting the calculation duration to 500 seconds, the FFT results of the wave height time series exhibit "amplitude aliasing" (one frequency corresponds to multiple amplitudes, as shown in Figure 1). Could you please help me understand the cause of this issue? The detailed input file is shown in Figure 2.

Thank you very much for your assistance.

Sincerely,
Ban Zhiqing.
